Help: Make policy CMP0126 wording more accurate
The OLD behavior only removes a non-cache variable of the same
name in specific circumstances. The previous wording implied
that it would always occur.
Also add a note about the behavior compared to the analogous
CMP0077 policy, which affects the option() command in a similar
but subtly different way.
